Chaivas international provides square well covers, model swc-01. Mild steel is the key ingredient of fabricated covers. The dimension of each of the square well cover is 4" x 4" x 39" [one metre]. These are protective covers for use in the drilling industry for the protection of the wells/pipe in the well and for periodic checking of the pipes, which these covers protect. Being bright blue in colour, they are easily identifiable as well as providing the needful protection from the elements of nature.
